4. Description of Mining: A. Top Soil: Aggregate Extraction begins with the removal and stockpiling of the topsoil using bulldozers and scrapers or excavators and trucks. Earth berms will be constructed to store the topsoil,provide screening of the operation, and reduce the equipment noise heard outside the operation area. These temporary berms will be constructed of topsoil from future areas to be mined and will be seeded. B. Phase Plan: Aggregate excavation will progress from the Northeast side of the property in a Southerly direction. Once to the Southeastern corner we will turn to the West once to the Southwest corner we will turn to the North and continue along the Northwest side.As mining progresses the processing area may periodically change to allow for the equipment to be as close to the excavation as possible. C. Aggregate: The current plan for processing aggregate utilizes a bulldozer pushing the uncovered aggregate material to a trap feeder, which- via a series of conveyors - feeds the material to a screening and crushing plant. The material is crushed and sized into various products, which are then stockpiled on site. The equipment typically used for this type of material processing includes a portable generator, multiple crushing and screening plants, and conveyors. The crushing and screening plants utilized by Midwest Asphalt Corporation are portable in nature. They can be moved within the extraction area as well as in& out of the operation as needed to replenish the product stockpiles. Once the products are stockpiled,we will use front-end loaders to place the material into over-the-road trucks,which haul the materials to either Midwest Asphalt Corporation's production plants,job sites,and use for our external customers.We will also as needed use a water truck and road grader on our haul road to 221st Ave.
